FAQs
What is LB1630?
The LB1630 is a dual-channel H-bridge motor driver integrated circuit (IC) designed for driving DC motors in various applications such as automotive systems, robotics, and consumer electronics. It provides bidirectional control of two DC motors with built-in protection features, making it suitable for driving motors in both directions.
How Does LB1630 Work?
The LB1630 operates by receiving control signals to drive the connected DC motors in forward, reverse, or braking modes. It incorporates H-bridge configuration to control the motor direction and speed. The IC also includes protection features such as overcurrent protection and thermal shutdown to ensure the safety and reliability of the motor driving system.
How Many Pins does LB1630 have and What are the Functions of the Pinout Configuration?
The LB1630 is available in various package types, such as SIP and SIL. The pinout configuration includes:
- VM, VCC: Motor power supply pins.
- IN1, IN2: Input pins for motor 1 control.
- OUT1, OUT2: Output pins for motor 1 connection.
- IN3, IN4: Input pins for motor 2 control.
- OUT3, OUT4: Output pins for motor 2 connection.
- VREF: Reference voltage pin for internal circuitry.
